I like Caleb for a boy, and Easton is okay. Can't say I like any of the girl names. They strike me as childish, and would likely have some people confused about her gender. Might I suggest:
Kayla
Kelila (keh LEE lah)
Caitlin
Kimi (KEE mee)
Kalia (kah LEE ah)
Kailea (kye LAY ah)
Cara
Kalina
Calista/Kalista
Carolyn
